QPR boss Redknapp was back at his old club for the first time since his sacking in 2012, but his hopes of avenging that surprise dismissal by chairman Daniel Levy swiftly evaporated as Tottenham ran riot.

Inspired by a sublime display from Argentine playmaker Erik Lamela, Spurs surged into a three-goal lead before half-time thanks to a brace from Belgian winger Chadli either side of defender Eric Dier's second goal for his new club.

Emmanuel Adebayor compounded Redknapp's misery when his strike put the finishing touch to the move of the match in the second half.
